VEN ETIAN BLIND.

SPECIFICATION forming part of Letters Patent No. 480,548, dated August9, 1892. Application filed November 24, 1891. Serial No. 412,975. (Nomodel.)

To all whom it may concern:

Be it known that I, JAMES K. BENWAY, of Albany, in the county of Albanyand State of New York,have invented a new and Improved Venetian Blind,of which the following is a full, clear, and exact description.

The invention relates particularly to the pulleys overwhich pass thecords for raising and lowering the slats of Venetian blinds,

1o the object being to improve such pulleys to the end that the slatswill respond tothe cords more smoothly and with precision and thehangers of the pulleys be prevented from marring the bar from which theyarey suspended.

The invention consists in the novel construction hereinafterparticularly described, and dened in the claims.

Reference is to be had to the accompanying 2o drawings, forming a partof this specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l. is a perspective view of a Venetian blind embodying myinvention. Fig. 2

2 5 is a detail View, partly in section and on an enlarged scale, of aportion of the upper bar and its immediate appurtenances, including myimproved pulleys; and Fig. 3 is a sectional perspective view, thesection being indicated 3o by the line 3 3, Fig. 2.

The blind shown in Fig. l is, in the main, in accordance with theinvention disclosed in United States Patent to J. E. Phillips, datedJanuary l, 1884, No. 291,222; but my irn- 3 5 proved pulleys areapplicable to other forms of Venetian blinds. In the form shown there isa frame or cornice A, provided at its top rail with depending hooks B,the latter engaging the journals o, formed on the top bar C, theblind-slats D being suspended in spaced positions from said bar bystrips E of webbing. In some cases hooks B are screwed into headjamb ofthe window, thus avoiding the use of cornice A. At one end of the bar Ca pulley C is secured, over which passes the cord F, whereby the bar C,and consequently the slats D, may be tilted.

The cords G, by which the slats are raised and lowered, pass over apulley H at the opposite end to the pulley C and over pulleys H', whichare suspended from the bar C intermediate its ends, the said cords Gpassing thence downward through the slats D to the bottom one of suchslats. Vith the exception of the pulleys H H and their means ofsuspension, as hereinafter described, the above parts are in accordancewith the patent of J.

E. Phillips above referred to.

The hangers H2 of the pulleys H H are formed, preferably, from a singlepiece of 6o metal bent upon itself, forming at the bend an eye h, ashank h below said bend, and a fork or spaced ends h3 below said shank,the pulley being held by a pin h4 between said spaced ends. Projectingfrom the members of the shank h', at right angles thereto, are wings h5,formed, preferably, by bending outward the metal forming such'shanks.

The upper end of each hanger H2 of the pulleys H is let into a;transverse recess or 7o slot c', formed in the under side of thebar C,which recesses are intersected by concave recesses c2,y formedlongitudinally in the upper side of said bar. A wire nail or like deviceH3 is passed into the upper recesses c2 to pass 75 through the eye 7L ofthe hanger, thereby suspending the hanger in secure position, Whilepermitting it to retain the vertical position when the bar O is rockedto tilt the slats. The wings h5, it will be seen, bear against one wall8o of the slot c when the cords G are drawn upon and protect the saidwall from any injury by the hangers, and also prevent the hangers fromtwisting. Further, in the tilting of the bar O the broad surfacepresented 8 5 by the Wings will prevent the hangers from catching in thewalls of the recesses.

By this improvement the operations of the blind are more positive andattended with less inconvenience, and the pulley-hangers 9o can in noway mar the bar from which they are suspended. The shank of the endpulley H is reversed, its wings lying against the wall or end c3 of thebar O, as the strain is inward on such hanger. The upper part of the barC overhangs at this end and is provided with a plate O3, which issecured thereto, and a nail H4 or the like, passed through said plate,through the eye h of hanger, and into the wall c3, serves to suspend thesaid hanger. roo

2. The combination, in a Venetian blind, of

u. top bar, slats suspended therefrom and operating-cords for the slats,the said bar having -zransverse recesses in its under side andinuersecting longitudinal recesses in its upper side, hangers carryingpulleys for the operating-cords, the hangers having wings thereon forthe purpose specified, and securing devices for said hangers,substantially as described.

3. As a new article of manufacture, a pulley for the cords of Venetianblinds, the hanger of the pulley having an eye at its upper end adaptedto receive a pivot-pin for pivotally suspending the pulley, and aguard-wing below the eye, said wing ranging at right angles to the axisof the eye, substantially as and for the purpose specied.
